4.

But since this man is the only one who has dared openly to mutilate the Scriptures, and unblushingly above all others to inveigh against God, I purpose specially to refute him, convicting him out of his own writings; and, with the help of God, I shall overthrow him out of those ¹ discourses of the Lord and the apostles, which are of authority with him, and of which he makes use. At present, however, I have simply been led to mention him, that thou mightest know that all those who in any way corrupt the truth, and injuriously affect the preaching of the Church, are the disciples and successors of Simon Magus of Samaria. Although they do not confess the name of their master, in order all the more to seduce others, yet they do teach his doctrines. They set forth, indeed, the name of Christ Jesus as a sort of lure, but in various ways they introduce the impieties of Simon; and thus they destroy multitudes, wickedly disseminating their own doctrines by the use of a good name, and, through means of its sweetness and beauty, extending to their hearers the bitter and malignant poison of the serpent, the great author of apostasy. ²
